Ultrafast light-driven electron slide discovered
When an intense laser pulse hits a stationary electron, it performs a trembling motion at the frequency of the light field. However, this motion dies down after the pulse, and the electron comes to rest again at its original location. If, however, the light field changes its strength along the electron's trajectory, the electron builds up an additional drift motion with each oscillation, which it retains even after the pulse. The spatial light i…
When an intense laser pulse strikes a stationary electron, the electron moves trembling at the frequency of the light field. However, this movement is extinguished after the pulse and the electron returns to its original location. However, if the intensity of the light field changes along the trajectory of the electron, it creates an additional drift motion at each [...]
Researchers at the Friedrich-Alexander-Universität Erlangen-Nuremberg (FAU) and the University of Rostock have discovered a groundbreaking effect in which electrons are already greatly accelerated by a single oscillation of a laser pulse. So far, this effect was only visible in long laser pulses and could now be observed by using extremely sharp metal needle tips.
